The meaning of the Dragonfly symbol was to signify happiness, speed and purity. The dragonfly also represents transformation and life's ever constant process of change. The dragonfly is a long tailed, four winged insect that inhabit the waters and wetlands of North America, as do many snakes. This symbolism is based on the life of a dragonfly which in first year or more of their lives, they live in the water as nymphs. They then metamorphose, change, into the flying creature we recognize as the dragonfly. The Southwest Indian culture use the term "snake doctor" in reference to a legend that dragonflies follow snakes around and stitch them back together if they are injured. For the Navajo tribe the dragonfly is the symbol for pure water.
